Drafted in the 6th round (183rd overall) by the Seattle Mariners in 2017 (signed for $245,600)

Jaskie has inspired others as he's been inspired by his developmentally-delayed older sister Hanna. Since arriving at Michigan, Oliver has gained plenty of good weight and nearly 10 mph on his fastball, turning him into a legitimate pro prospect. His delivery has some effort, but also some funk and deception. He has racked up plenty of strikeouts for Big Blue (11.65 K/9 IP, 16th in Division I) by working inside to righthanded hitters with his 87-90 mph fastball, setting up his average changeup that has some late fade. His fringe-average slider has a little potential as well, making him a potential lefthanded reliever with enough funk and deception to survive.
